Today, I experienced the same issue with my computer. It powers on for 30 seconds and then restart, endless loop. I found the Bios to the issue with my ASRock z390 phantom gaming 4-CB (yes.. cyberpower).

I don't have the means to downgrade the CPU from i7-9700kf to 8 series or the time, so here's what worked for me:

Reset the motherboad CMOS
1. remove the GPU
2. locate the cmos battery and remove
3. find the cmos jumper and short for 20 secs.
4. replace the the battery
5. replace the gpu
6. turn on computer. It will start in Cmos
7. set the time and date, save and exit
8. System should reboot into the os

Now you should be able to flash the bios.

I hope this work for others...]]> Tue, 17 Dec 2019 22:28:28 +0000 https://forum.asrock.com/forum_posts.asp?TID=11269&PID=71227&title=z390-phantom-gamingitx-ac-not-starting#71227 https://forum.asrock.com/forum_posts.asp?TID=11269&PID=69910&title=z390-phantom-gamingitx-ac-not-starting#69910 Author: Klax

I just powered on my system and have the same issue. However, I have bios version 4.00. Just sent a message to tech support.]]> Wed, 13 Nov 2019 19:29:32 +0000 https://forum.asrock.com/forum_posts.asp?TID=11269&PID=69910&title=z390-phantom-gamingitx-ac-not-starting#69910 https://forum.asrock.com/forum_posts.asp?TID=11269&PID=69822&title=z390-phantom-gamingitx-ac-not-starting#69822 Author: tormyh

Really happy with it so far, hope it lasts a long time :)]]> Sat, 09 Nov 2019 23:22:24 +0000 https://forum.asrock.com/forum_posts.asp?TID=11269&PID=69822&title=z390-phantom-gamingitx-ac-not-starting#69822 https://forum.asrock.com/forum_posts.asp?TID=11269&PID=69821&title=z390-phantom-gamingitx-ac-not-starting#69821 Author: MikaelS

Go to the page https://www.asrock.com/MB/Intel/Z390%20Phantom%20Gaming-ITXac/index.asp#BIOS and download the "INSTANT FLASH" of newer version, you might try 4.00 first. Unpack the files and copy them to a USB Stick formatted with FAT32. Then plug the usb stick to one of those Nr. 15 as per manual USB ports and reboot. If it reboots automatically, just let it do this for quite a while, obvioulsy at some point in the reboot processes it possibly triggers an "automatic" attempt to update the bios from a usb stick.

Thanks for this. I've given it a shot but without luck.

The problem is that it never gets to POST, so there is no way it can detect the USB flash update.
